Ford 7700 (A) or Hanomag Robust 901 A (S)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the 7700 (A) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Robust 901 A (S) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Ford 7700 (A) suits loader and hydraulic implement work better on this data: 28% (9.0 L/min / 2.4 gpm) more hydraulic flow.
- The Ford 7700 (A) suits road haulage better on this data: 10% (2.9 km/h / 1.8 mph) more top speed.
Generated by rule set compare@4 from the figures on the side-by-side table, allowed by route “the same stated configuration”. Measured figures are compared only with measured, claimed only with claimed, at the same test condition; differences within each figure’s tolerance are not called.

What does this mean in plain words?
- The Ford 7700 (A) has 28% more hydraulic flow (9.0 L/min / 2.4 gpm) than the Hanomag Robust 901 A (S) (both pump flow, as stated by the source).
- The Ford 7700 (A) has 33% more forward gears (4 gears) than the Hanomag Robust 901 A (S) (both forward gears, as stated by the source).
- The Ford 7700 (A) has 10% more top speed (2.9 km/h / 1.8 mph) than the Hanomag Robust 901 A (S) (both top speed forward, as stated by the source).
- The Ford 7700 (A) is newer: production began 7 years later. We hold no parts-availability data, so there is no call on parts.
- Even on weight (both unladen weight, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on PTO speeds: the same speeds (540, 1000 rpm).
- Even on PTO independence: every PTO is independent.
- Even on drive: every machine is available with four-wheel drive.
- Not comparable on power at the PTO shaft: the 7700 (A) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Robust 901 A (S) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, three-point lift, maximum permissible mass and a creeper range.
